Uni appears in the Etruscan text on the Pyrgi Tablets as the translation of the
Phoenician goddess Astarte. Livy states (Book V,
Ab Urbe Condita) that Juno was an Etruscan
goddess of the Veientes, who was
ceremonially adopted into the Roman pantheon when Veii was sacked
in 396BC. This seems to refer to Uni. She also appears on the Liver of
Piacenza.

With her husband Tinia and Menrva, she was part of a
powerful triumvirate.
